I am getting a unstable reading from 1762-IT4 module...jumping up and down, but only when the heating element is on. Here is what I got, a single type J thermocouple to 1762-IT4 moudle, the thermocouple is connected to a block of metal heated with one 120v element, element is controlled by 4-20ma proportinal SS contactor. I am controlling heat with PID in the ML 1400. Here are the 1762-IT4 settings I have,10hz filter, upscale, degrees F, thermocouple J, scaled for pid.
Any help would be great!!
Thanks
